制备具有与底层设备对称性根本不同的哈密顿量基态是量子技术的核心挑战。本文针对该挑战，提出一种模拟协议，用于基于线性几何（开放边界条件）上的磁化保持相互作用、由周期边界条件产生平移对称性的标志性广义簇哈密顿量。结果表明，该目标可在控制时长内实现，该时长仅随自旋数量和哈密顿量相互作用复杂度适度缩放。
英文摘要
The preparation of ground states of Hamiltonians with symmetries that are fundamentally different than those of the underlying device is a central challenge for quantum technologies. Here, we address this challenge with an analog protocol for the iconic generalized cluster Hamiltonian with the translational symmetry resultant from periodic boundary conditions based on a magnetization-preserving interaction on a linear geometry with open boundary conditions. Our results show that this goal can be achieved in a control duration that scales only moderately with the number of spins and Hamiltonian interaction complexity.
